I also thought about including promoted girls. I don't know how our schedule should look like.

It's a bummer that i can't add more than one poll to this thread. I could create three threads every week for three rainbow girls but that would be inconvenient. People are basically forced to switch between threads to discuss every girl individually which kinda sucks.

Any suggestions are much appreciated.

My two cents about Black Baccara:

She has high Attack, good HP and above average Def.

I can see her work in an AEO Damage Squad (basically a squad utilizing this Ability: Increases Attack for party members by 15% multiplied by the number of remaining enemies on the field when combat begins.) An Atk Increase of 45 % is really strong considering most pest groups consists of three enemies anyway.
Her Skill Act. Buff is average but always n1 to have. She buffs herself and another team member for 65 % atk (130% atk total) which makes her a hard hitting AOE-Girl.
I don't understand why the devs decided to give her the defense Buff Ability. All other Abilities of Black Baccara are obviously designed for Offense. She works best in an offensive team and her defense buff does little there.

Her Speed being 400 (Borderline Snail) is a big bummer at least for me. I like Squads with balanced Speed stats. BB's Speed slows the Squad's overall Speed down by a significant amount.

An AOE Damage Squad has potential in my opinion and so has BB. Imagine 5 girls who all buff the Atk of the whole team for 45 %. That's a total buff of 225 % atk without even applying the normal atk buff. In all other offensive Archetypes she is decent.

Is BB necessary in an AOE Squad? No. But she especially shines there.

I wavered for a long time between B and C-Tier but in the end i went with B-Tier because i really think AOE Damage Stacking is a good Archetype.
